We numerically investigate the dynamics of quantum droplets (QDs) forming in one-dimensional (1D) binary Bose gases held in optical lattice (OL). It is found that the OL potential strongly influence the stabilit
In the three-dimensional system, we know very well that the global correlation can overcome the local disturbance, such as the removal of one atom, to be a solid at low temperatures. This is because there are many more paths along which the correlation can grow than in one dimension. In ...
Here we take a key step towards establishing the relationships between structure, forces and response dynamics needed to address that challenge by investigating OA of the important oxide semiconductor ZnO. ZnO readily forms quasi-one-dimensional nanostructures and is a canonical example of a functional...

Phagraphene is a newly proposed two-dimensional allotrope of carbon. Its structure resembles that of a defective graphene sheet. The unit cell structure of phagraphene consists of a 5–6–7 ring sequence due to which it possesses lower energy than most carbon allotropes. Phagraphene has properties...
Our results revealed that it takes about 0.7 ps for the 1s A exciton to reach quasi-equilibrium; a characteristic time that is associated with a rapid population transfer from the 1s B exciton, providing rich characteristics of many-body exciton dynamics in two-dimensional materials. 1 School ...
We analyze the dynamics of one-dimensional quantum gases with strongly attractive contact interactions. We specify a class of initial states for which attractive forces effectively act as strongly repulsive ones during the time evolution. Our findings extend the theoretical results on the super-Tonks-...
We also introduce a variable timestep procedure to account for the disparity between slow nuclear motion and fast electronic fluctuations.; Our mixed quantum-classical method is applied to the study of three simple one-dimensional two-state models. The first model represents the photoinduced ...
We introduce optical forces on molecules by optical lattices in Section 2 and present a kinetic description of molecules within a quasi-one dimensional (1-D) optical lattice in Section 3, where we formulate the ensemble motion of molecules with the 1-D collisionless Boltzmann equation. In ...
steeper efficiency scaling of the extreme ultraviolet harmonics as a function of the driving-field intensity25and a higher cut-off energy26for crystalline materials, pointing to the importance of long-range order in condensed-phase HHG, which has also been explored for one-dimensional models27,28....
